That said, I remember someone suggesting a cable or chain for standard bike, but run inside the saddle post and saddle tube. I don't know how you can fasten it to the frame inside the tube (BB? Bottle cage eyelets? Something else?) and whether that would interfere with the folding mechanism.

My guess is that he's a multi-modal commuter and can't bring a normal bike on the RER/Métro but uses it on both ends, therefore, leaving it locked outside during the work day. I'd have a very hard time believing that any Parisian would allow a bicycle, even a folding one, inside.
